EDGE-SETTING MAGHINE; &

Toiall whom it-ma'y concern:

B it known ,thatywe, ERAsrUs ENVINK- LEY and Benjamin PHILLIPS, citizensof the'United States, residing at Lynn, in the county of Essex'and Stateof Massachusetts,

have invented certain'new and useful Improvements in' Edge SettingMachines; and

We do hereby declare the following to be a full, clear, andexactdescription of the invention, suchas will enable others-skilled in theart to which it appertains to make and' use the same. V

I The invention relates to machines for setskill or care on the part ofthe operator. l

To this endonef eature of the invention contemplates the" provision in amachine provided with a shoe sup orting jack of a plurality ofedgesetting evices the points of operation of which are transferredalong different parts of the sole edge by a relative movement of thejack and setting devices While rapid relative movements are beingimparted to the jack and setting devices to efiectively rub or burnishthe edge as the point of operation is transferred along the sole. Theburnishing movements of the setting devi ceswitli 'relation to the soleedge secure a rapid and uniform finishing of the edge" at the point ofoperation, while the provision of a plurality of such rapidly operatingedge setting/devices for operating upon different parts of the shoeenables the burnishing of the 'sole edge to be quickly completed.- i

It is irsual in the manufacture of boots and shoes, and especially 'ofthe better grades, to give th'e sole edge a different shape along theshank from'that given to the soleedge around the iorepart of-the shoe.,

The. burnishingor setting of the sole edges 1 of such shoes.th'ereforerequires the use of differently sha ed setting devices inoperating upon thed ifferently shaped parts of "the sole edge.

Accordingly a further feature of the invenv tion contemplates theprovision in a machine in which relative burnishing movements andrelative movements toltransfer thepoint of op-. eration along the soleedge, are imparted'to a shoe supporting jack and edge setting devices,

of edge setting devices having sole: engaging different partsofthe bleedge. It is not material to this feat-u e of the invention,

broadly considered, whether the differently shaped facesof the settingdevices actupon they different partsof the sole edge simultaneously orsuccessively. In the preferred embodiment of -the invention,however,'the difierently shaped faces of the setting devices actsuccessively on the different parts of the shoe sole, and means reprovided for shifting the edge setting de ices to bring the" ing uponthe sole edge 'on opposite sides of theshoe, and of a separateed esetting tool for operating upon the soles ge at the toe of the shoe, andthe invention also.contemplates the provision of separate jacks and edgesetting devices for right and for left shoes.

'Other features of the invention will be noted in connection with thedescription of the illustrated embodiment thereof.

The illustrated embodiment of the invention is a duplex machine beingprovided with two jacks and two sets of edge-setting tools, and being.adjusted to operate upon right-hand shoes -iipon one jack and left handshoes upon the other. The jacks ar'' I similar in construction. As shownparticuoted a'heel pin 2, which enters a socket in larly in Fig. 4,eachja'ck comprises a heel post 1, upon the upper end of which is pivthelastand is pressed forward by a spring. plunger 3 so as to tilt the shoeagainst the toe support. The heel post slides vertically in a sleeve 4fixed to a slide 5 mounted upon horizontal ways -'6 upon the bed plate 7of the jack. The slide 5 may be moved horizontally on the ways 6 toaccommodate the jack to shoes of differentlengths, and by means of ahand screw S it is fixed in adusted position. The toe post 9carries, atits upper end the toe support-10, which-is provided wlth circularcurved'ribs 11 loosely engaging corresponding grooves in the raised soas to press the shoe upward against the fixed heel and toe rests 14 and15. The heel rest 14 is provided with a rocking arrangement 16 like thatof the toe support, and is mounted upon an arm 17 projecting from theframe of the machine. The toe rest 15 is similarly mounted upon an arm18. The compensating lever (see Fig. l) is mounted upon the upper end ofa rod 20, slidingly mounted in the frame of the machine, and the-lowerend of the rod 20 is embraced by a sleeve at the upper end of a link 21pivoted at its lower end to a treadle lever 22. A sliding collar 23 onthe rod 20 engages the lower end of a compression spring 24 which bearsat its upper end against a collar fixed on the rod 20. A catch 25 ispivoted upon the frame of the machine in position to engageand retainthe collar 23 when it is moved upward to compress the spring 24, and ahand lever 26 is connected with the catch to release' it when necessary.

To insert and secure a shoe on the jack the bed plate 7 is drawn towardthe operator along horizontal ways on a bracket'19 pro- ]ecting from theframe of themac hine, and

the lasted shoe is then placed upon the heel.

post. The bed plate of the jack is then pushed back until the toe is inposition under the toe rest and the operator then depresses the treadle,thereby compressing the spring 24 which operates through the rod 20 andcompensating lever 13 to raise the heel and toe post and press the shoeupward against the heel and toe rests. The catch 25 engages the collar23 and maintains the jack in this condition until released by thehand-lever 26.

In connection with each jack there are provided edge-setting tools.ofthree kinds. the shank tools for burnishing the sole edge The toe fromthe heel to the juncture of thei s'hank and theforepart, the foreparttools for burnishing the sole edge from 'the'latter oint to the toe,aridthe toe tool forburm' lshing the forward extremity of the soleedge.The shank and ,forepart tools are mounted upon heads 27 (see Figs. 4and'?) fixed to the forward ends of shafts 28 journaled in sleeves 29.The rear'extremities. of the sleeves 29 are provided. with forks 30pivoted in uprights 32 (see Figs. 4, 5 and. 6) upon sleeves 33 rotatablymounted in sleeves 34 projecting downward from slides The slides areprovided with flanges 36 engaging corresponding ways on the frame of themachine, so that they may be moved longitudinally with respect to theshoe to transfer the point of operation of theedge setting tools alongthe sides of the shoe.

The pivotal mounting of the sleeves 29 per? mits' the tools to rise andfall in accordance with the contour of the sole edge as the-tools aremoved longitudinally with respect .to the shoe. To maintain the tools incontactwith the sole edge each sleeve 33 is provided with an arm 37 towhich is connected one end of a spring 38. the other end being fixed tothe slide 35. This spring tends constantly to swing the sleeve 29- in adirection to press the tool against the'sole edge. The burnishing toolsare given a constant vibration along the sole edge of slight amplitudeto facilitate the burnishing operation. For this purpose the rear endsof the shafts 28 are connected'bv universal joints 40 with links 41pivotallfv connected with eccentric straps 42 engaging eccentrics 43 onshafts 44, j ournalecl in uprights 45 on the slides 35 and provided withsuitable driving pulleys 46. This arrangement is such that a constantand rapid vibration may be im parted to each tool without interferencewith its several other movements. I

In order that the operation'may proceedfrom the heel to the toe of theshoe it is necessary to impart to the tools, in addition to theirvibrating movement above described,

a general movement longitudinally with respect to the shoe, and for thispurpose the slides 35 are moved horizontally in the frame of themachine. As shown in Fig.

4, the slide of the right-hand lastis connected by means of a short link47 with the upper end of a lever 48 fixed (as shown in Fig. 1) upon arock shaft 49 j'ournaled in the frame of the machine. This rock shaftlever is actuated by a cam 50 on the cam shaft 51 of the machine throughsuitable connections to be described later.

As shoes are usually finished with edges of different form in theshank'and in the forepart, it is necessary, after the edge has beenburnished front the heel to the forepart. to substitute a different toolto operate upon the forepart, and the present machine is provided withshank tools 52 and forepart tools 53. These iools are mounted upon ashort shaft 39 loosely journaled in the head 27, so that thetoolsinayturn to accommodate themselves to the inclination on the soleedge, and means are provided for automatically substituting the foreparttool for the shank tool at the proper time in the operation of themachine by imparting a half rotation to each of the shafts 28. For thispurpose each shaft is provided with a gear wheel 54 located at the rearextremity of the sleeve 29 and splined to the shaft 28. This gearengages a toothed sector on a bell-crank lever 55 pivoted at 56 in thesleeve 33 and having a lateral arm connected by means of a link 57 witha lateral projection from a sleeve 58. The sleeve 58 slides verticallyupon a rod 59 fixed at its upper end to the sleeve 33. The lower end ofthe sleeve is grooved, and is engaged by the forked end 62 of abell-crank lever journaled at 63 on a bracket 64 mounted on the slideThe bell-crank lever carries a cam roll (35 engaging a cam path 66 in acam disk (37. The cam is mounted upon and splined to a cam shaft 68passing loosely through the bracket 64 but fixed against longitudinalmovement at its rear end, (see Fig. 1) where it is journaled in theframe of themachine. In order that the forepart tool may be substitutedin this manner for the shank tool it is necessary to swing the latterout of engagement with the sole edge, which is accomplished by turningthe sleeve 33 slightly in the slide 35. and for this purpose the arm 37is provided with a cam roll 69 engaging a cam path 70 (see Fig. 4) inthe cam 67. It is also necessary before swinging the shank tool out ofengagement with the sole edge to lock the sleeve 29 in its verticalposition with respect to its pivotal connection with the uprights 32, inorder that the forepart tool when substituted for the shank tool mayoccupy the same vertical position as was occupied by the shank tool,corresponding to the height of the sole edge at the point of change. Tothis end the rock shaft 31 (see Fig. 6) upon which the fork 30 ismounted, is keyed to the fork. and upon its outer end is fixed adepending arm 72 carrying a curved friction surface 73 in position to beengaged by a corresponding brake shoe 74. The brake shoe is mounted upona horizontal lever 7 5 pivoted to the upright 32 at its outer end itsinner end with a link 76 bearing upon a lever '77 pivoted upon thebracket 64 and carrying a cam roll engaging a cam path 78 in the cam 67.

r The operation of the mechanism just described issuch that when apartial rotation in the direction of the arrow, Fig. 6, is imparted tothecam 67 by the rotation of the cam shaft (38, the sleeve 29 is firstlocked in and connected at its vertical position, then swung outwardlyfrom the shoe to remove the shank tool therefrom and then a halfrotation is imparted to the shaft 28 to reverse the positions of thetools. The sleeve 29 is then allowed to swinginward again until thefcrepart tool engages the sole edge a d the brake shoe Ttthen disengagesthe riction surface 73. After the edge-setting operation has proceededfrom the heel to the toe,

a partial reverse movement of the cm 67 takes place, therebysubstituting the shank' tool for the forepart tool in readiness for theoperation upon another shoe. But the cam dwells in such position as toleave the shank tool out of contact with the sole edge and fixed in itsvertical position, to permit the finished shoe to be removed and a newone to be inserted. After the machine is again set in operation. the cam67 at once completes its return rotation to the p sition of Fig. 6. topermit the shank tool to engage the sole edge.

The mechanisms above described are repeated for each pair of tools,there being four such pairs in the (\UDlQX machine, and the four camshafts ()8 are connected to operate in unison by means of beveledpinions80 at their rear ends engaging pinions 81 on a transverse rock shaft 82jpurnaled in the frame 'of the machine. To actuate these shafts at theproper time one of the shafts (see Fig. 2) is provided with a pinion 83engaging a segment 84 on a bellcrank lever 85 journaled on the frame ofthe machine and provided with a depending arm 86 carrying a cam rollengaging a cam 87 on the cam shaft 51.

The outer edges of the left-hand shoes and the right-hand shoes aresimilar in character, so that the slides 35 corresponding to these partsmay be moved in unison. and for this reason the slide corresponding tothe outer side of the left-hand jack is actuated moving in unison withthe lever 48. The I inner edges of the two soles are also similar toeach other but not to the outer edges. and therefore a single mechanismis used to ac tuate the slides corresponding to these edges. thismechanism operating, however, differently in point of time from theother slideactuating mechanism, as will be described.

As has been shown, the tool-changing mechanism operates at a fixed timein the cycle of operations of the machine forboth jacks and for both theinside and outside edges of the shoes. but, as is shown in Fig. 7, it isnecessary that at such time the inside too-ls shall. ave advancedfarther toward the toes than the outside tools, owingto the greaterlength of the inside of the shank, so that it is necessary to providemeans for varying the longitudinal movement of the several tools duringthe operation of the &

portion previous to the changing of the tools. Furthermore, in operatingupon different styles of shoes it is necessary to make furtheradjustments, as the relative lengths of the shanks and foreparts differin different styles. For these reasons the lever -18 is connected withits actuating cam 50 through an adjusting mechanism. The lever isprovided with a curved slot 90 engaged by a slide block 91 which may befixed in adjusted position therein. A link 92 is pivoted to the block 91and at its rear end is connected with a bell-crank lever 93 pivoted at9-1 upon an arm 95 loosely journaled upon a shaft 109 lixed in the frameof the machine and carrying a roll engaging the cam path 98 in the cam50. At the upper end 100 of the arm 95 is pivoted a curved arm 99provided with a T-slot engaged by a slide block 101 which may be fixedin adjusted position therein. A link 102 connects this slide block v.ith a lateral arm 103 on the bell crank lever 93. A pin 10 1 projectinglaterally from the forward end of the arm 99 engages a curved slot in acam plate 105 fixed to the frame of the machine. It will be seen thatwhen the arm 95 moves rearwardly under i the influence of the cam path98 in the cam 50 it carries the arm 99 with it. .The bell crank lever 93tends to rotate to the left and leave the lever 48 unmoved. but thistendency is resisted by the link 102 and the arm 99, and the latter isprevented from swinging upward by its connection with the cam plate 105,and thus when the arm 95 swings back the arm 18 is also swung back, witha motion modified in accordance with the form of the cam plate 105.acting through the connections described. The cam plate is provided witha slot having two portions 106 and 107, the portion 100 being traversedby the pin 101 prior to the exchangingof the shank and forepart tools.while the portion 107 is traversed thereafter. The shape of the portion107 such that it causes no movement of the arm 99 with respect to thearm 95, and the arm 99 is so curved with i respect to the link 102 inthe bell crank lever that whatever the adjustment of the slide block 101maybe. the movement of the lever j 48 is not affected by this mechanismafter 1 the tools have been exchanged. The portion l 106 of the cam pathdoes. however. modify 2 the movement of the lever 18. By moving theslide block 101 in the arm 99 the extent of this modification may beadjusted. and in this way the mechanism may be so arranged t that withincertain limits of variation the j shank tool may be adjusted to attainany desired position upon the sole edge at the time l of exchange of thetools. The curved slot 90 and the slide block 91 afford provision forvarying the amplitude of movement as a whole of the lever 48, to

j comprising a link adjust the machine for shoes of difierent lengths.

The longitudinal movements of the inside tools are effected through alever 110 loosely journaled on rock shaft -19 and actuated, throughadjusting mechanism similar to that above described, by means of a campath in the cam 87, and this arrangement permits of the independentadjustment necessary, as above pointed out, owing to the differencebetween the inside and. outside edges of the Soles.

The cam shaft 51 is set in motion automatically by ,the depression ofthe treadle by which the shoe is fixed in position on the jack. Aworm-wheel 121 fixed to the cam shaftengages a worm-114 on a shaft 115driven by a pulley 11G loosely journaled thereon. A clutch 117 operatesto connect or disconnect-the pulley and the shaft, and is thrown into orout of operation by a rod 118 sliding longitudinally and provided with abell-crank lever 126. A spring 119 engages brackets 120 in which the rod118 slides, and tends normally to move the rod to the left (Fig. 1) tothrow the clutch into engage ment. This is prevented, however, while themachine is out of operation by a lug.123 fixed to the worm-wheel'124 andengaging the upright arm 122 of the bell crank lever 120. therebyholding the lever and the rod 115" to the right. I The horizontal arm ofthe bell-crank lever is connected by a link 127 with an arm 12S fixed toa rock shaft 129 'carrying another arm 112 pivoted to the link 21. 'henthe treadle is depressed the arm 112, shaft 129 and arm 12S operate,through the link 127. to rock thebell-crank lever so that its uprightarm 122 is disengaged from the lug 123. The spring 119 then operates tothrow the clutch into engagement and the rotation of the wormwheelcommences in the direction of the arrow. Fig. 1.

The forward extremity or toe of the sole is operated (Fig. 8). The toetool has a rocking connection 1 32 with a depending arm 133 piv' oted at134 in a yoke 135. The yoke 135 has horizontal arms 130 and 137 looselyjournaled upon a vertical shaft 138. The shaft 138 is journaled in thearm 18 and an arm 139 on the frame of the machine. The toe tool hasrapid oscillations of small amplitude imparted to it by means ofconnections 110 connecting the yoke 135 with a bell-crank lever 111,pivoted at 112 in a yoke having horizontal arms 143 pivoted upon theshaft 138. The bell cranklever 111 is pivoted at 14:5 to an eccentricstrap 146 engaging an eccentric on the shaft 138. A pulley 1 18 fixed onthe shaft rotates it constantly athigh speed, thereby actuatthe bellcrank lever and one of the.

upon by a separate tool 12-31 ng. aneecentriqfland, through theconnections above described, imparting a rapid vibratiomto' the toetool. vibration it. is necessary to swing the yoke 135 throughaconsiderable arc to cause the too-tool to vv'ork all around-the toe, andfor this purpose a gear segment 150 is fixed to the arm- 143 and engagesaraek bar 151 slidingrhorizontally in-the frame of the machine. Therack.bar (see Fig. 2) engages a gear segment 152 on a lever 153 pivoted inthe Y frame of the machine, and provided with-a cam rollengaging a campath in-a cam 154 mounted on a shaft 155 journaled on the frame of themachine. The shaft 155 is connected by asprocket chain 156 with the camshaft 51 so as-to-rotate in unison therewith. The cam ath is so formedthat the toe tools, starting fromtheir' left-hand position, as shown inFig. 2, are swung to a corresponding right-hand position while the s ankandifo art tools are advancing toward the toe, so that the toe isburnished or.

set at the same time as the side edges of the sole. During. itsoperation the toe tool is held in contact with the sole edge by means ofa spring 157 engaging the arm 133 and a rod 158 passing looselytherethrough and fixed in a depending lug on the arm 137.

It is necessary to remove the toe tool from the soleedge before theforepart tools reach the toe, to-afl'ord'room for the latter to opcrate,and for this purpose each of the depending arms 133 is provided with ahorizontalarm 159 in position to be engaged by the curved extremity 160of a lever 161 fixed to a rock shaft 162 journaled in the frame of themachine. The rock shaft 162 has an arm163 provided with a cam rollengaging a cam path 164 in the cam 154 (see Figs. 1 and 2). At theproper time in the operation of the machine the arc-shaped members 160are raised, thereby engaging and lifting the arms 159 and swinging thetoe tools away from. the sole. This position is maintained by thetoe-tools until another shoe is inserted in the machine and itsoperation is resumed.

The machine above described is capable of operating uponshoes of allsizes and styles with slight adjustments which may be readily made bythe operator, and by the use of shank tools and forepart tools, withautomatic means for exchanging them at the proper time in the operationof the machine, the machine is adapted to produce exact equivalents ofthe results produced at Work from one tool to another.

In addition to this i of the operator to remove and replace the Work.
